Hooked - dog fin tuna barotrauma?
Ok, So im watching some tv and theres a show called hooked and they were with some nz Boat designer and celeb fisherman in Aus I think in the coral sea. They were trolling lures and cameras going for dogfin tuna, some great shots but when they finally boated a est 1.5 mt 70kg tuna and went to release it, it was knackered with "a problem with its swim bladder from pressure differential after being brought up" isnt that barotrauma? So they haul the fish back on board after watching it flounder around on the surface in shark infested water (the other hookup got sharked). Their remedy? A release weight? No, They knife the swim bladder and let it go. Is this a good way to deal with it over the release weight? Or something because the fish was so large?
Also with all this stuff today on the forums about extra species being added to possibly make the v21 due to bycatch survival problems. How does the rest of Aus compare from us in legislation and education?
I dunno, straight after they went on a rant about dynamite fishing leading to habitat destruction enviro rant and they were trying to catch and release. But what is the right way?

before release weights
puncturing the swim bladder was the accepted method to relieve the pressure build-up. But it can lead to infection amongst a host of other problems. The release weights are in some regards uniquely WA. Its not a worldwide phenomenom or anything. They were initially developed as a better way to get sambos back down.
But from a survival point of view, the release weight is best, but if you dont have one, then puncturing the swim bladder to release the pressure is better than nothing.

Good doggy
Yeah good doggy that one. He vented it with a proper venting needle sarcasm0. From what I know of the species they are very susceptible to barotrauma and it was probably the best solution rather than having the doggie slowly fed to the bottom on a release weight.

They suffer with a bit of
They suffer with a bit of both really. Not as bad as Dhus but they also suffer from what Sambos do as well with the lactic acid.

And I personally would not like to try to get a release weight in the mouth of a dogtooth tuna especially of that size. There is a reason for their name

I've caught doggies in 20m
I've caught doggies in 20m of water that wouldn't release. There was no insides coming out of the mouth or anything but they had a very tight stomach area and wouldn't go down regardless. These were caught on trolled laser pros so they were hooked in the first few metres of water and ran back to the bottom so it's not like we reefed them up from the deep.
